“This comprehensive series of tests will show us whether the proposed battery improvements will work as designed,” Transportation Secretary Ray LaHood said in a press release. “We won’t allow the plane to return to service unless we’re satisfied that the new design ensures the safety of the aircraft and its passengers.”
